Just went through another CCW class, this time for the Idaho "enhanced" which allows me to get rid of my non-enhanced Idaho & Utah permits...Well it made me think some more about modified triggers in carry guns & the liability target if I ever needed to defend myself or others...
9 years ago I installed a Wilson Combat Custom-Tune #321 J-frame spring kit (used the heaviest option of 15# rebound trigger spring as well as it's 8# Hammer Spring)...I never actually measured the original springs but it was a lot heavier/grittier...
So My curiosity gets me on Amazon & I ordered the Lyman Electronic Digital Trigger Pull Gauge...Once I get the technique down to eliminate all the erratic hang up & over-pulls (as high as 11#), my last 10 measured pulls averaged 4# 1.3 oz. & I've never had a light strike? Makes little sense to me but I'm going to reinstall the original springs back in...and measure again.
I also tested the accuracy of the gauge, placed a 7# barbell inside a 1 gallon ziploc bag & test hung...which measured 7# 3.3oz which seems close enough. I also figure technique errors in measurement would only result in high (?) readings...don't know how a bad angle could result in a low reading.
Any thoughts?
When I re-install the original springs I'll post up the results...This 642 no lock has MAYBE 40 hurtful rounds through it...but a thousand dry fire practice w/ snap caps using laser for movement watching.
